I've been posting fanfic online for over a decade now. As a fandom butterfly, I've written for a zillion different series.
At this point pretty much everything I've ever written for any fandom is on AO3 (minus a few WiPs). You can also check out my livejournal to see what fandoms I'm currently into.
If you would like to post a podfic of my stories, or fan art or a comic, or write a remix or a sequel to any of my fics, you have my blanket permission to do so with anything I've written, as long as you give me credit for the original story. (I'd love it if you let me know what you make, but you're not obliged) If you would like to archive my stories on a separate site, or translate them into another language, please do ask me first; I'll almost definitely say yes, but I want to know where they end up.
